MCP23016, Serial Peripherals - 16-bit I/O Expander
The Microchip MCP23016 is a 16-bit input/output
expander designed to provide embedded systems with
general purpose remote I/O expansion through an
I
to inputs and can be confi gured as inputs or outputs.
Additionally, there are four sets of registers that are
programmable and provide for confi guration (input or
output control), output value, and polarity (active low
or high). The MCP23016 open drain interrupt (INT)
output is activated when any input state differs from
its corresponding input port register state. By sending
an interrupt signal on the interrupt logic of the master,
this remote slave device informs the master that
there is incoming data on the port without having to
communicate via the I
pins (A0, A1 and A2) vary the fixed I
allow up to eight devices to share the same bus.
The MCP23016 has low current consumption and
includes latched outputs with high current drive
capability for directly driving LEDs.
